Application led May '7, 1903. Serial N0- l56,()ll. (No model.)

To all whom zit muy concern:

Beit known that I, EDWARD F. MCINTYEE, a citizen of the United States,residing at St. Paul, in the county of Ramsey and State of Minnesota,have invented certain new and useful Improvements in Oar-Locks; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same,reier ence being had to theaccompanying drawings, and to the figures of reference marked thereon,which form a part of this specification.

My invention relates to improvements in oar-locks; and the object of the.invention is to provide a cheap, simple, but efficient oarlock of theclass which cannot be accidentally removed from the boat, but may beeasily detached therefrom, and which when on the boat Vplate 6, whichmay be termed the frame,

or seat of the oar-lock. N ear the middle'` of the frame is formed avertical socket i', in which the round shank 8 of the fork or oarlockproper, 9, is dropped. Said shank is provided with an annular recess 10,in which engages the tooth 11, secured in a Hat springarm 12, which hasits upper end secured at 13 in a vertical recess 14, formed in the outerside of the frame next to the gunwale, so that the spring-arm playsbetween the gunwale and the casting and has always a tension toward thegroove 10 of the shank, so that when the latter is to be removed theoperator must press on the lower end of the spring away from the shank,and as the shank is inserted in the socket the slant of the point of thetooth 11 or the cone shape of the end of the shank, or both, force thespring toward the gunwale until the recess 10 can receive the tooth,when the spring comes back to its normal position, and thus locks theshank in place against accidental re- .movaL V Among the advantages ofthe device as compared to any earlier devices in its line is theinverted form'of the recess or pocket 14, in which the spring-arm issituated so that no dirt, ice, or snow can accumulate in it and obstructthe action of the spring. It is also very cheap and simple to make, inthat the rivet orstud 13 vmay be made of malleable iron .integral withthe plate 6. The spring `itself may be stampedvor cut from band-steelfrom which the catch 11 may `be formed integrally. The finger-catchformed of the freeLY with a vertical recess upon the side nearest EDWARDF.
